New study indicates Apple is the top single manufacturer, but there's a few disclaimers to consider

Internet
data mining isn't the most accurate way to track smartphones, as it can be
biased by usage patterns; that said it does give a decent rough estimate of
market share. Market research firm ComScore's latest internet
traffic-based market share
analysis delivers the controversial conclusion that Apple is
the top single smart phone manufacturer in the United States.

Before proclaiming "Apple is #1!", it's important to point out that
this is not a “by operating system” market share comparison. If you
combine the market shares of Motorola Solutions Inc. (MSI),
Samsung Electronics Comp., Ltd. (SEO:005930), HTC Corp. (TPE:2498), and LG
Electronics Inc. (SEO:066570)
(11.4, 8.9, 11.8, and 4.8 percent, respectively) you get 36.9 percent, nearly
50 percent more than Apple's 26.6 percent. Granted, those manufacturers
also sell Windows Phone 7 handsets (Microsoft Corp. (MSFT)),
but that market share is likely only a small percentage of that total.

That said, Apple deserves plenty of credit for earning the top spot in this
ranking -- especially since it only has two relatively old products, the iPhone
4 (12 months old) and iPhone 3GS (2 years old), on the market.

Other interesting observations are that despite all the doom and gloom surrounding Canadian
smartphone maker Research in Motion, Ltd. (TSE:RIM),
it still is maintain a sporty 24.7 percent market share. It's also
telling that Microsoft's favorite hardware partner, Finland's Nokia (HEL:NOK1V),
could only muster a meager 2.1 percent market share.

Apple, along with Microsoft are suing Android's top handset makers to force
them out of the top spot -- or out of the market altogether. And Apple is
also eagerly awaiting the launch of a new iPhone in September, which is
expected to be a relatively minor refresh.
